is passed, the door swinging about the axis ofthis pin. Such hinges are subject to the disadvantage of rusting or corroding so that they work less easily than when in good condition and also particularly in the case 0f heavy doors the parts develop' considerable friction'so that it is advantageousto place an anti-friction bearing between the knuckles which will take the weight of the door and reduce the friction between parts.

One object of this invention is to overcome the disadvantage referred to above and provide a door hinge which will operate easily at all times and be practically noiseless in operation.

A further object of the invention is to provide a hinge of this character with antifriction bearings which bear the weight of the door so that the parts of the hinge will move with greater freedom.

3u Another object of the invention is to provide a fibre bearing for a door hinge of this character so that the parts will operate with less friction and the bearing itself will be durable and economical to manufacture.

To these and other ends the invention coiisists in the novel features and combination of parts to be hereinafter described and claimed.

In the accompanying drawing:

open position embodying my improvements; Fig. 2 is a sectional view through the hinge pin;

Fig. 3 is an enlarged fraginental sectional view through the knuckle to which the bear- 50 ing a modification.

Fig. l is an elevated view of a hinge in'4 To'illustrate a preferred embodiment of Vmy invention, I have shown ahingeconiprising a pair of leaves 10 and 11, one of which is adapted to be secured to the door frame and the other to the door. The leaf 'V 55 l0, as shown, is provided with 'the knuckles 12, 13, and 14, and the leaf 11 vwith the knuckles 15 and 16 which are adapted to-bc received between the knuckles on the leaf 10. All of the knuckles, as shown on lig. 0

2, are provided with aligned openings through which may be passed the hinge pin 17 to secure the two partsV of the hinge together. In the usual form this hinge pin* may be readily removed so that the two 5 parts ofthe hinge may be detached.

It will be apparent that in the form of Vmy invention shown, the knuckle 13 is of less height'thaii the other knuckles and upon. each end of knuckle 13 is mounted abearing "i0 unit, one of which is adapted to receive the weight of the door depending upon the position in which the hinge is used. These bearing units are alike and one only thereof will A be described. jI5

These bearings comprise a cup shaped container having a side walllS anda bottom wall 19,.the bottom wall having a central opening for a passageof the hinge pin. Within this container are Ymounted a pairso of hardened steel washers, 20 and 21', one

`of which is adjacent. to the upper end and the other adjacent the bottom of the container. It will be noted that the peripheral edge of the upper or. outer washer 20 is 85 somewhat tapered lin shape so that the upper edge of the side wall 18 of the container may be displaced and crimped inwardly to secure the washer 2O in place. c Between the washers 20 and 21 isjplacedf-Qo awasher 22 which I prefer to form of fibre.

ThisffibreV washer 22 is placed between the hardened steel washers and may be lubricated with a dry lubricant, as graphite or the like, which will prevent any tendency of y the adjacent surfaces of the steel-.washers to rust, and at the same time to provide for free turning of Vall of the washersrelatively to each other. It will, of course, be-understood that the washers are assembled'within''lO the container with sufficient freedom so as to permit of this turning movement. The libre washer 22 when placed between two hardened washers in this manner, provides` a bearing which operates with extremely little friction and one which is very durable, being, able to withstand a great deal of use without having to be replaced.

It will be noted that the upper washer 20 projectslslightly above the sidewall 18 of the container so that the adjacent knuckle of the companion leaf of the hinge rests up on this washer and will not bear Aagainst the container which may not always be free to turn.

If it is desired to secure the bearing to the hinge knuckle, this may be effectively done by passing a tubular sleeve` member 23 through the? bore of the knuckle, aroundthe hinge pin 17 and securing the ends of this sleeve to the lower portion 'of the bearing unit. The ends of the sleeve aresecured to a portion of the unit below all of the bearing washers so that all of the latter are left free to turn.

In the form of my invention shown in Fig. 8, the bottom portion 19 of the container is relatively thin. and I find it desirable to place adjacent to bottom 19 an additional washer 24. The opening through this washer is slightly beveled outwardly and upwardly as shown in 25.-V

Theunit consisting of the container and the four washers, 20,21, 22, and 24 may be slipped over the sleeve 28 after the latter has been placed within the knuckles and the end of the sleeve entering the container is then expanded over the lower washer 24 and the bottom of the container. The use ofthe Washer 24, which may be made of steel, affords reinforcement for the relatively thin bottom 19 of the container, and when the end ofthe Vsleeve 23 is expanded over the vbeveled edge 25, this provides a secure method of fastening the bearing in place. The

lower bearing washer 21 may be provided withl a counter-bore 26 which faces downwardly so that` the washer will clear the expanded end of the sleeve 23 to prevent friction between the parts. v

In Fig. 5 of the drawing, I have shown a somewhat modified form of the invention v in which Athe washer` 24 is omitted. The bearing unit in this instance comprises the containerhaving the side wall 18a and al relatively thick bottom wall 19a within the container, and the washers 20a, 21aand 22a,

`which are similar in all respects to the corresponding parts shown in Figs. 1 to 4. Y In this form of the invention, the outer endsv of the sleeve 23a are expanded over the bevfeled Aedge of the opening in the relatively thick bottom 19a of the container.- When the bottom of the container is made relativelyheavy and strong as in thisformvof `washerstend to turn with thehinge pin, theyz'will be permitted to do so without any 4o f the knuckle and engaging said washer to my hand .this 26 day of December, 1929.

my invention, the additional Washer 24 may be omitted. The operation of this form of the invention is, however, precisely the same as that of the form shown in Figs. 1 to 4.

It will be apparent that when the sleeve 23 (or 23a) lis secured to the bearing unit below the bearing washers, all of the three washers are left free to turn as such movement is required, and should any of these friction with the securing sleeve.

While I `have shown and described some retain the container on the bearing and bearing members withln said container above the washer.

In witness whereof, I have hereunto set Jenn wELLnR.
